FAURE Q 5 I MEANS FOR MOISTENING CERAMIC ARTICLES WHILE SHAPING THEM Filed Aug. 5, 1930 Patented Jan. 5, 19 32 UNITED STATES PATENT OFFICE JEAN MARIE ANDRE FAURE, or EmoGEs, FRANCE, ASSIGNORJTO SOCIETE A. FAUBE a 01E, 0]? LIMOGES, FRANCE MEAN S FOR MOISTENING CERAMIC ARTICLES WHILE SHAPING THEM Application filed August 5, 1930, Serial No.

In moulding ceramic articles a soft paste is applied to a plaster mould and gauged by means of a shaping tool. During these two operations it is necessary to moisten with water the surface of the paste that is being worked. When the material is placed upon a revolving support and the tool remains stationary it is easy to apply water to the revolving surface by means of a sponge or a' jet, but when the material to be worked remains stationary and the tool revolves, this tool forms an obstacle to the application of water to the surface undentreatment.

The present invention consists in damping the material worked by means of a device which is applicable even when the tool is revolving.

The invention consists essentially in sprinkling the article with a mist of water atomized by air under pressure by means of atomizers mounted upon the tool-holder and revolving with it, these atomizers being fed paste a to be worked is placed upon a fixedmould band is subjected to the action of arevolving tool '0. The latter is carried by a this blast pipe, is concentrically arranged'a wider nozzle j, to which air is supplied.

The-water and the air arrive through pipes a I: and Z respectively, which start from dis- 'tributing. chambers m and n.

reaches the chamber m through a tube 0, arranged in. the axis of the sleeve 6. In

The water- 473,273, and in France September 26, 1929.

alignment with the tube 0 is located a stationary tube p for the admission of water, which is surrounded by a stuifing-bow gland q;

Air under pressure is admitted into a stationary box 1- through a tube 4). Apertures 8 place this box in communication with the annular space tbet ween the tube 0 and the sleeve 6. I

Water being admitted into the tube 12 and air under pressure being passed through the tube 12, these fluids arrive in the chambers m and n, from which they are distributed to the atomizers. By opening the needles u to a greater or less extent a larger or smaller quantity of water is admitted. This water is atomized by the air and forms a mist, which produces a satisfactory sprinkling of the article that is being made. The little drops of waterare very fine and reach all points of the article, but there is no excess of water anywhere.

Since the atomizers revolve with the tool, the latter does not in any way hamper the access of the moistening mist to the article under treatment.

The arrangements described above are of course only given by way of example, and the details of construction and operation can be varied without in any way affecting the principle of the invention.

Claims 1. Apparatus for mo'istening the paste during the shaping of ceramic articles, comprising arevolving tool adapted to shape an article on a fixed mould, a tool holder, and an atomizer on the head of the tool holder.

-2. Apparatus for moistening the pastean axial conduit for one of said fluids, a second conduit concentric with the-first conduit and serving for the passage of the other fluid, said conduits revolving with the sup- 5 port, and a stationary box traversed by the two conduits and receiving one of the fluids and supplying-said fluid to the second mentioned conduit.

for moistening ceramic articles while shaping them, signed by me this 25day of July,
